Patent EP-0370598-A1 (EP)
Inventor: BREWER JOE EARL
IPC: H05K7/20
Filed: 1989-07-06
Abstract: Wafer scale integrated circuit apparatus wherein a full wafer scale semiconductor integrated wafer (10) is adhesively secured to an essentially flat heat conducting non-metallic base member (12) with the wafer and base member having coefficients of thermal expansion ap­proximately equal to one another. A cable adapter assembly (42) connected to an edge (43) of the base member secures one or more multiconductor flat cables (46) in position such that the conductors thereof, by means of a clamping arrangement (64), make positive pressure contacts with contact points (18) connected to electronic circuitry (16) of the semiconductor wafer. Another wafer (11) may be placed on an opposed surface of the base member and a second cable adapter assembly (82) may be utilized to secure another multiconductor flat cable (87) for making interconnection between contact points of the wafer on one surface with contact points of the wafer on the opposed surface of the base member. The arrangement constitutes a wafer module (40) and a plurality (100) of such identical wafer modules may be stacked one upon the other and placed in a housing (102) which has heat conducting side walls (104, 105) for heat dissipation purposes. A cable link assembly (60) traverses the flat cables held in position by the first cable adapter assemblies of the wafer modules in order to serve for the inputting and outputting of electrical signals.

Abstract: A gantry (A) of a CT scanner system has an x-ray tube (10) and radiation detectors (14) which produce patient diagnostic data. An operator using a keyboard (20) or other controls operates the x-ray tube and other components of the gantry. The operator also causes a central processing unit (C) to process the diagnostic data with a selected algorithm to provide diagnostic information for display on a display (24). The same keyboard and displays are also utilized in routine service and repair processes. A system monitor (E) compares operating conditions sensed by sensors (50), such as detector temperatures and compares them with acceptable operating conditions. When the sensed conditions are unacceptable, a timer (60) is started and shuts down gantry operation after a preselected duration. The operator can override the timed shut down, but each such override is recorded in a memory (32). The comparing means also compares software identification codes either for software selected on touch sensitive areas (76) of the display screen or from new software identifications read on a disk drive (22). If the identification of the requested or received software matches an authorized software identification, the software is utilized for diagnostic or service purposes. Other use of the software is blocked and the identification of any software sought to be entered is stored in the memory. To initiate a CT scan, a ready button (40) starts a timer (44) which enables a start button (42) to control the power to the CT scanner for a selected short duration, e.g. 30 seconds.

Abstract: The tool (10), such as a pneumatic gun, places inserts, in particular inserts with a central hole, one by one. An insert loader (5) is slidable in the front end (2) of the tool body and comprises a longitudinal channel (52) and a lateral insert-injecting channel (53) which communicate with one another via an orifice (57). A push rod (6) is slidable in the longitudinal channel and may possess a gripping device (66). A piston (23) of a single-acting pushing cylinder (2) is integral with the loader and advances the loader (5) which opens the orifice (57) for the passage of an injected insert (1) which is stopped by retractable lugs (54). A spring (25) moves the loader (5) back so that the stopped insert is held by the gripping device (66), and that the lugs (54) are retracted by the push rod (6). Finally, the held insert (1) is completely visible at the front of the tool (10) in order to centre it on the hole of a component. The push rod (6) is immovable as the loader (5) is moved forward and back, and is struck by the rod of a rear piston in a single-acting cylinder with compression chamber counter to a return spring, in order to implant, with a very high force, the held insert into the component hole. <IMAGE>

Abstract: The invention relates to a process for annealing metal work pieces in a protective hydrogen gas in a furnace, wherein, to reduce the amount of protective gas required and as an additional process parameter, gas with a higher density than hydrogen is blown into the leakage openings of the continuous furnace, for example and in particular at the inlet (11) and outlet (4) of the furnace and is thus mixed with the protective gas situated there, whereas in the rest of the continuous furnace the hydrogen-enriched protective atmosphere is maintained in accordance with the heat treatment to be carried out. <IMAGE>

Abstract: A stream of gas is passed through at least one chamber whose entry and exit orifices are offset to produce a turbulent flow throwing the larger-sized particles against the walls of the chamber. At least a proportion of the stream of gas is removed out of this chamber through a porous downstream wall trapping the finest particles. The filter consists of two walls (1,5) of different lengths, connected to each other along alternate folds (2,6). The downstream wall (5) consists of a porous fibre mat. The two walls (1,5) are provided with offset openings (4,8).

Title: Switching power supply circuit
Inventor: HARTMANN UWE ING-GRAD
IPC: H02M3/28
Filed: 1990-02-24
Abstract: The subject matter of the invention is a switching power supply for high powers, which has a switching power supply transformer TI with a primary main winding WI1, a primary-side driver winding WI2 and a secondary winding WI3 for supplying a regulated voltage rail (voltage Us) and which is provided with an electronic switch 2, connected in series with the primary main winding WI1, which switch 2 interrupts at high frequency the DC voltage applied to the primary main winding WI1. According to the invention, at least one further switching power supply transformer TII is provided which likewise has a primary main winding WII1 and a secondary winding WII3 supplying the regulated voltage rail. The primary main windings, on the one hand, and the secondary windings for supplying the regulated voltage rails, on the other hand, are connected mutually in parallel. As a result of the use of two separate switching power supply transformers TI and TII, considerable advantages from the functional viewpoint and the production-technical viewpoint are achieved with respect to the known switching power supplies, which have only a single switching power supply transformer.

Abstract: The noise behaviour of the piston pump is to be improved. 
<??>The piston pump has a drive shaft (13), which has a cylindrical tumbling journal (14) bent at an acute angle ( beta ) to its longitudinal axis (O) with a rolling bearing ring (18) arranged on the peripheral side. A pump piston (21) acts with its end face (27), designed as part of a spherical surface, on the circumferential surface (29) of the rolling bearing ring (18). The longitudinal axes (O, P) of the drive shaft (13) and of the pump piston (21) run in a common plane and intersect at right angles. In addition the longitudinal axes (O, T) of the drive shaft (13) and the tumbling journal (14) are staggered. By means of this configuration a delivery phase considerably longer than the intake phase is achieved during a pump cycle. Changes in pressure and force therefore occur more slowly in the extended delivery phase, which improves the noise behaviour of the piston pump (10). 
<??>The piston pump (10) may be used, for example, in vehicle brake systems for delivering brake fluid.

The receiving slot (25; 225) for the pivot pin (24; 224) is formed on the frame (12, 15; 215). The lowering hook (20, 20'; 220) has an elongate guide slot (22; 222) with which a guide pin (23; 223) attached to the frame (12, 15, 215) is in engagement and around which the lowering hook (20; 220) can be swivelled in the case of movement into the locking position with displacement of the guide pin (23; 223) along the guide slot (25; 225). When moving into the locked position, before reaching said position the lowering hook (20; 220) passes through an intermediate position in which the engagement element (201; 301) is lowered further than in the locked position so that the lowering hook (20; 220) is held in the locked position in a self-locking manner. …<IMAGE>…
